I have a 93 SI with supposedly its a 97-01 jdm h22 in it. i have to replace my thermostat and coolant temp. switch. For every year the switch is the same size according to car shops. but idk cause its a jdm or what. my switch uses a wrench lil bigger tha a 7/8s and the ones they keep giving me are way smaller in size and threads to screw into my thermostat housing or w/e u wnna call it. idk what to do. do i have to get a jdm one? are they diff....?
